What is the preferred method of resolving unhandled exceptions in Node.js?

Câu trả lời

The preferred method of resolving unhandled exceptions in Node.js involves several strategies, primarily focusing on the use of process-level error handlers. The most common and recommended approach is to attach a handler to the process.on('uncaughtException') event. This method is widely advocated because it captures exceptions that have not been caught by try-catch blocks, thereby preventing the Node.js process from crashing unexpectedly[2][3][4][6].

Additionally, it is important to note that while process.on('uncaughtException') is effective for synchronous code, asynchronous exceptions require careful handling to ensure they are not missed. For asynchronous code, using process.on('unhandledRejection') is recommended to handle promise rejections that are not caught elsewhere in the code[1][4][5].

Moreover, while the uncaughtException handler is a critical part of error handling in Node.js, it is generally advised that this should be used as a last resort. The best practice is to write robust code with adequate try-catch blocks and proper promise handling to catch ...
